It's a bit off-topic, as it is in no way related to the other question, but meh...

I have always used uloader in combination with an emulated wii nand (on USB drive). If you have this same setup, it will automatically install to this emulated nand (on USB:\nand) and ignore the wii nand completely. No idea what'll happen if you run it without having an emulated nand...I guess it'll install to the real nand, but I'm not sure. Maybe it'll even put the containing files in further empty USB:\nand\title0474141 and USB:\nand\ticket0474141* folders.

*random numbers in this example: it depends on which wiiware you install
